Embodiment Construction

[0038] The invention imports the original data measured by various instruments into the data summary table of the database system, and then performs operations such as data playback, data preprocessing, data editing, data interpretation, and result output according to user needs, which is the follow-up of the system. Jobs provide convenient, reliable, and fast data processing objects.

[0039] Concrete steps of the present invention are as follows:

[0040] Firstly, establish the oil well information table (WellStatics) and the logging team information table (TeamInfo);

[0041] Import the raw logging data in curve, spectrum, wave train, two-dimensional table or stream format obtained by one of the logging tools, and preprocess the raw logging data; the logging data can include sectoral cement cementation, multiple Parameter logging, C / O ratio, C / H ratio, new C / O ratio, new C / H ratio, chlorine energy spectrum, gadolinium tracer energy spectrum, energy spectrum tracer, neutron...

Abstract

The invention relates to a petroleum-logging data processing method. The method comprises the following steps: (1) establishing an oil well information table and a petroleum-logging team information table; (2) importing original petroleum logging data which are measured by a petroleum-logging instrument and are in formats of curves, spectrums, wave trains, bivariate tables or streams; (3) pre-processing the original petroleum-logging data; (4) establishing a corresponding basic information table according to the pre-processed petroleum-logging data; and (5) establishing a summery data table which at least includes an oil well mark, a petroleum-logging team mark, a start depth, an end depth, a data category, a processing mark, a table name and comment information. The invention solves the technical problems of very complicated data processing steps, data retrieval and inconvenient comparison and check in the prior art and has the advantages that the information management of an oil wellcan be realized, petroleum-logging data in any format in the prior petroleum-logging technical field can be saved, and the like.

Description

technical field [0001] The invention relates to a method for processing petroleum logging data. Background technique [0002] Existing petroleum well logging data is data of multiple sets of different data structures obtained by logging instruments with different performances. However, the logging data has the following problems: [0003] 1. The amount of data is large, and the processing steps are relatively complicated, requiring the user to wait for a long time to obtain the required logging results; in addition, due to the long processing time, when the user uses the data next time, the system cannot give the last processing process , processing steps and processing methods, causing problems such as double counting or missing counting. [0004] 2. Many well logging data have different formats, which makes it inconvenient to retrieve, compare and verify the data. Contents of the invention [0005] The purpose of the present invention is to provide a method for process...
